ABSTRACT
The appearance of emerging variants of SARS-CoV-2 carrying mutations into the spike protein has recently raised concern with respect to tracking their transmission and mitigating the impact in the evolving pandemic across countries. AY.4.2, a recently detected Delta variant sub-lineage, is considered a new variant under investigation (VUI) since it carries specific genetic signatures present in the spike protein, called Y145H and A222V. Here using genomic epidemiology we provide the first preliminary insight regarding the circulation of this emerging VUI in Italy. This article is protected by copyright. All rights reserved.
